Abstract
The invention belongs to the metallurgical industry and relates to an alloy powder which is used for improving hardness of metal surface materials, improving corrosion resistant performance and abrasion performance and prolonging service life of equipment, in particular to high carbon and high chromium alloy self-fluxing powder. The high carbon and high chromium alloy self-fluxing powder comprises, by weight, 6.2% of carbon, 2% of boron, 2% of silicon, 32% of chrome, 7% of manganese and the balance ferrum. The high carbon and high chromium alloy self-fluxing powder is applied to equipment of the coal-mining industry and the cement industry in order to improve corrosion resistant performance, abrasion performance and hardness. At the same time, time is saved, and production efficiency is improved. According to high carbon and high chromium alloy self-fluxing powder, the original surface hardness of metal materials is larger than 58 HRC, and compared with the abrasion performance of the existing metal materials, the abrasion performance is increased by 40-50 times.
